Abstract (en)

[origin: EP0675588A2] A method is described for controlling the input current drawn by a switching power converter notwithstanding wide variations in load being supplied by the converter. The input current is controlled in response to a first signal. An input current control signal is generated based on comparing a second signal to a third signal. The second signal is independent of variations in the input current or the first signal. The third signal is dependent on variations in the input current and the first signal. The input current control signal is arranged to drive the value of the third signal towards the value of the second signal. The third signal is maintained and the magnitude essentially equal to the magnitude of the second signal. <IMAGE>
